# How to swap into a swap pool that is depleted

Check pool liabilities and reserves on the [swap pools](https://app.nabla.fi/swap-pools) page.

## Pool Liabilities

\
Liabilities describe the amount of assets deposited by the LPs. The pool is liable since LPs are entitled to withdraw their assets any time.

## Pool Reserves

\
Reserves describe the amount of assets in the pool at a given time. <br>

## Balancing Pools

\
For example, if the USDC pool has 1M liabilities but 800k reserves, this means you need to "swap into" the USDC pool to balance it. \
\
You should [swap](https://app.nabla.fi/swap) USDC for any other asset. By swapping, you add USDC to the USDC pool reserve, while subtracting from the pool reserve of the asset you swap for.

\
LPing does not change the depletion because if you add more as an LP, the liabilities increase as the pool needs to pay back more tokens. &#x20;
